HAY-SLING LOCK.

Specification of Letters Patent.

Fatented. Jan. 1 2, 1909.

Application fil d April 28, 1908. Serial No. 49,591.

city of Goshcn. county of Elkhart, State of Indiana, have invented certain new and useful Improvements in Hay-Sling Locks, of which the following 15 a specification.

This invention relates to improvements inhay sling locks.

The main object of this invention is to provide an improved hay sling lock which is simple and compact in structure, and one which is very strong; also, one in which the parts may be easily and quickly engaged and also easily disengaged while under the strain of the load.

Further objects, and objects relating to structural details, will definitely appear from. the detailed description to follow.

I accomplish the objects of my inventioi'i by the-devices'and means described in the following specification.

The invention clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in-the accom panying drawing, forming a part of this specification, in which,

Figure 1 is a plan of my improved hay sling lock, it being shown substantially in full size as manufactured. Fig. 2 is an inverted plan thereof. Fig. 3 is a detail tion, taken on a line corresponding to line 3 3 of Fig. 1, showing the hook member in engagement with the eye member. Fig. 4. is a detail section taken on a. line corresponding to line .l:-thf Fig. 2, showing the arrangement of the latch pivot and latch spring, the pivot being shown in full lines.

In the drawing, the sectional views are taken looking in the direction of the little arrows at the ends of the section lines, and similar numerals of reference refer to simi lar parts throughout the several views.

Referring to the drawing, the hook mem her 1 is provided with a laterally-pro}ccting engaging portion 2 at its outer end, the engaging portion being preferably cylindrical in form and. slightly tapered, as is illustrated.

The eye member 3 is provided w't-h an eye l adapted tOlliCGlVc the hook, the eye being large enough so that the hook The eye is also preferably provided with an outwardly-projecting portion 5 over which the hook mem- Eber fulcrums, so that the members are readily disengaged when the latch 15 re leased. The eye member is provided with eye, andthese raised portions have openings 8 and 9, respectively, therein adapted to receive the latch 10.

i The latch 10 is mounted on 'a pivot 11 arranged on the inside of the raised portion 6. The swinging end of the latch is arranged through the opening 9 in the opposite raised portion and is provided with a hole 12 in which the rip rope may ,engaged. The opening 9 is of such dimension that it holds the latch against lateral movement. By locating the pivot on the inside of the raised portion 6, it is protected so that it is not likely to be engaged on exterior objects; also the strain on the latch, instead of being borne by the pivot,'is largely borne by the body of the eye member, the strain on the swinging end of the latch being also borne by the body of the eye member, or the raised portion 7 thereof. This arrange ment securely supports both ends of the latch and provides an arrangement of the parts which allows the latch to be disengaged by comparatively slight movement, the friction of the hook member thereon be ing comparatively slight as it only engages on the end of the hook member. This also enables the making of the parts comparatively light in weight, and, at the same time, they possess very great strength. The latch is held normally in its engaging position by leans of a spring 13, which is arranged on the latch pivot 11, one arm of the spring, as 14-, being engaged through a. hole 15 located centrally of the eye member, and the other arm, as 16, being engaged over the latch. This forms an effective support for the spring which may be made comparatively long and so located that it is practically impossible that it should be injured in use by becoming engaged with some object, .or the like, it being entirely surrounded and will clearly appear from an inspection of the drawings. Another advantage of arranging the swinging end of the latch through the opening 9 is that effective stops for the latch are thereby secured.

While 1 have illustrated and described my structural simplicity and convenience in use,

raised portions 6 and 7 at each side of the improved hay sling lock in detail in the. form preferred by me on account of its" protected by comparatively heavy parts, as

1E ,Lclaim as new .ters Patent is:

I am aware that it is capable of considerable variation in structural details Without departing from my invention. V

Having thus described my invention, what and desire to secure by Let- In a structure of the'class described, the combination with a hook member having -a laterally-projecting engaging portion; an eye member having an eye therein adapted to receive the member, said eye member having raised portions relative,to said eye at each side, said raised portions having transverse openings therein; a latch; a pivot for said latch arranged on the inside of one of said raised portions, the swinging end of said latch be ing arranged through the opening in the -other raised portion, said opening being ZO 'adapted to hold 'the swinging end of the latch against lateral movement, said latch being adapted to-swing over the end of the hook When the same is engagedin the said eye; and a spring coiled about said latch pivot havin one end arranged through a central openlng in said eye member and the other engaged on said latch whereby the same is held normally in its engaging posivtion, said eye and hook members being proengaging portion of said hookvided with holes adapted to receive the ropes to be connected.

2. In a structure of the class described,

the combination with a hook member having a laterally-projecting engaging portion; an eye member having an eye therein adapted to' receive the engaging portion of said hook member, said eye member having raised portions relative to said eye at each side, said raised portions having transverse openings therein; a latch a pivot for said latch arranged on the inside of one of said raised portions, latch being arranged through the opening in the other raised portion, said latch being adapted vto swing over the end of the hook when the same is engaged in the said eye; and a spring whereby said latch is held normally in its engaging position, said eye and hook members being provided with holes adapted to receive the ropes to be connected.

In'witness whereof, I have hereunto set my hand and seal in the presence of two Witnesses.
